Klinefelter's syndrome and acute leukemia
Cancer Genetics and Cytogenetics
|June 1, 1987
Summary
Klinefelter's syndrome (47,XXY) may increase cancer risk, but acute leukemia appears uncommon. A review of 1200 patients found only one with acute leukemia and Klinefelter's, suggesting no elevated risk compared to the general population.
Area of Science:
- Oncology
- Genetics
- Hematology
Background:
- Klinefelter's syndrome (47,XXY) is linked to a higher risk of certain cancers.
- Previous reports suggest a potential association between Klinefelter's syndrome and acute leukemia.
Purpose of the Study:
- To investigate the actual incidence of acute leukemia in patients with Klinefelter's syndrome.
- To determine if Klinefelter's syndrome confers an increased risk for acute leukemia.
Main Methods:
- Retrospective review of 1200 consecutive patients.
- Cytogenetic investigation for hematologic malignancy.
- Analysis of patient data for diagnosis of acute leukemia and Klinefelter's syndrome.
Main Results:
- One patient with acute leukemia and 47,XXY karyotype was identified.
- The incidence of acute leukemia in this cohort was low.
Conclusions:
- The findings do not support an increased risk of acute leukemia in patients with Klinefelter's syndrome.
- The risk of acute leukemia in Klinefelter's syndrome patients appears comparable to the general population.
